This human study at 7T presents the great potential of ultra-high
resolution UTE imaging to simultaneously visualize cartilage, meniscus,
ligament, tendon, and even the chondro-osseous junction in the knee joint, critical
to understanding the onset and progression of osteoarthritis.

(long white arrow) and the chondro-osseous
junction
(red arrow, black region) in the ultra high resolution UTE image at 7T
for
the same subject as in Fig. 1: a) full

A suspicious defect is clearly visible on
the
chondro-osseous
junction above the red arrow in b).
